88% Polyester 12% Spandex UPF 50+ Sun Protection Single Jersey Knit is a plain single-bed knit developed for Running Tops where low weight with fast moisture transport decides whether a style succeeds. The base is 88% polyester filament / 12% spandex, which gives the workhorse blend for training ranges that wash repeatedly. The result is a fabric that delivers UPF 50+ Sun Protection in daily use rather than only in a laboratory.

Why this construction works
Because a plain single-bed knit is used, the fabric behaves consistently across the roll: the lightest way to get coverage, with good stretch and a clean surface for printing. That consistency is what lets a factory cut confidently and lets a brand repeat an order a season later with the same result.

Recommended applications
Used for Running Tops and for the accessories around them. low weight with fast moisture transport is the reason it is chosen, and the fabric bonds, prints and sews on standard machinery without special settings.

Dyeing, finishing and customisation
The fabric can be supplied greige, piece dyed or printed. Add-on finishes are selected after a wash durability trial, because a finish that disappears after five washes is worse than no claim at all.
Care instructions
- Machine wash at 30 degrees with mild detergent, no fabric softener.
- Dry away from direct heat and do not tumble dry hot.
- Cool iron on the reverse if needed, and avoid bleach.

Frequently asked questions
What is the minimum for a first order? Development starts at 300 metres per colour, which is enough for a proper wear trial and a small capsule. Bulk pricing improves at 1,000 metres and above per colour.
Can the weight and width be changed? Yes. Most programmes run between 140 and 340 GSM, and width can be set between 150 and 180 cm to match your marker. Changing weight changes cover and stretch, so we re-test before confirming.
